5. Security rules
To a oid electrical shock, scale or other connected
peripheral de ices damage, it is necessary to follow the
security rules below.
• To supply the scale use power outlet with protecti e contact (not for
scales with external feeder).
• Repairs and essential scale regulations can be made only by authorized
personnel.
• To a oid fire risk use a feeder of an appropriate type (supplied with a
scale). Pay attention that supply oltage is compatible with specified
technical data.
• Do not use a scale when its co er is opened.
• Do not use a scale in explosi e conditions.
• Do not use a scale in high humidity.
• If a scale seems not to operate properly, plug it out of the mains and do
not use it until checked by authorized ser ice.
6. ules proceeding with used up scales
According to obligatory rules concerning en ironment
protection used electronic de ices should not be put in
a container with normal waste.
• After exploitation used scale should be gi en to special units authorized to
collect used electronic equipment or to the place where the de ice was
bought.

8 ENGINEERING DOCEMENTATION
_____________________________________________________________________________________________________________________
7. Assembly and connecting external devices
1. To build a scale basing on ME-01 indicator contact authorized manufacturer
ser ice point or use Installation Guide deli ered with the indicator (other
brochure).
2. The manufacturer gi es a full guaranty for ME-01 indicator only when the
indicator was mounted by AXIS Sp. z o.o. In other cases the guaranty obligation
is taken o er by the final contractor of the weighing de ice.
To comply CE marking requirements, for connecting the wires use filtering core
φ20mm.
The core should be placed within 30mm from the place of its connection.
Single strain gauge scheme inside ME-01:
When 6-wires connection of strain gauge transducers is used (REF+ and REF)
jumpers shown on the picture abo e should be soldered out from the main board
Before connecting the sensors to the indicator unplug the device from the
mains to avoid damaging the indicator.

Transmitter connection
P1-P3 (THRESHOLDS) outputs are used to connect dosing or signalling (option)
de ices. There are opto-isolators of an open collector type with 100mA / 24V
maximum load. They can be connected directly to transmitters inputs or to
MS3K/P board offered by AXIS separately or in ST 3K/P control box (3
transmitters, own power supply).
In ME-01/A connection THRESHOLD is placed on indicator’s housing. In
ME-01/N meter connection is placed on conductor.
Optional indicators outer wires ha e digital markers.

Outputs are adapted for direct connection RM96P transmitter of DC24V input
oltage and AC250V 8A output. Transmitter’s coil has to be secured with diode
e.g. 1N4148.
It is recommended to use MS 3K/P electronic board (3 transmitters of RM96P
type – max. load of 3A/250V) or complete ST 3K/P control box (feeder, 3
transmitters like abo e).
The way THRESHOLD outputs work is described in the separate document
(Special functions description).
7.2 External key connection
The input of external keys allows to place (make double) selected scale keys into
control box or operator’s workstation. As a standard the input is taken out with a
wire for direct connect to a control panel. ME-01 indicators can be equipped with
external key interfaces (as an option on demand).

External key connecting is shown below. It is crucial to use external supply (24V)
in order to make current flow through scale transoptor input. This way of
connection pro ides gal anic separation of the scale from automatics system
which increases resistance to external interference and increases reliability.

8. Scale start
Connect the feeder to supply socket and the while the pan is unbiased connect
feeder’s pins to scale’s 12V socket.
This will cause following sequence of actions:
Display test.
Base electronic components test
signalized by: C-1, C-2, ...,C-4 .
Program ersion display.
Weighing readiness.
Attention:
Displaying program ersion means

9. Operating rules
1. Before each measurement make sure that zero indicator is displayed. If zero
indicator does not displayed or “----“ communicate appears, press →0← key
and wait until zero indication and zero indicator appears
2. The scale is equipped with tare equal to its measurement range. To tare the scale
press →T← key. In order to make mass control on pan easier and a oiding
o erflowing measurement range, scales with LCD display ha e load indicator
scaled 0÷100%.
3. Weight result should be read out while indicator is displayed (this indicator
means that the measurement is stable).
4. When there is no need to weight and only stand by mode is necessary , the scale
can be turned off using I/ key. This will switch off scale reading out system
and turns the scale to readiness state signalized by OFF indicator(scales with
LCD display). Turning on the scale is made by pressing I/ key. After autotests
the scale is ready to work with full precision.
5. Weighed sample should be placed in the centre of the platform.
6. The scale should be protected from dust, aggressi e pollens and fluids. To clean
it, it is ad ised to use a wet rag with soap and afterwards dry it.
7. The scale is equipped with accumulators (option), automatically charged while
normal work with connected power supply. Charging control take place thanks
to special function bAtterY. This function enables readout of charging state of
accumulators and also it can turn off the charging in case using batteries instead
of power supply. Discharged accumulator is displayed by BAT indicator on
LCD display, and then after about 1 hour work, the scale switches off
automatically (it switches off before the accumulator discharges underneath
oltage threshold alue).
After discharging indication appears, accumulator should be quickly connected
to external power supply. Charging is more efficient when the scale is turned off
by I/ key, charging time takes then about 10 hours.
Do not drop weighed objects on pan. To avoid this, it is
recommended to place the scale on a platform.
Do not overload the balance above 20% of maximal load (Max .
Complete discharging can damage the accumulator.

ENGINEERING DOCUMENTATION 15
_____________________________________________________________________________________________________________________
10. Scale verification
While scale exploitation, in order to check balance efficiency, before and after
measurement series it is ad ised to check weighing precision by putting on an
object with well known mass.
To check legalized scale a special actual standard of mass should be used. If the
measurement error is bigger than allowable legalized scale error, contact
authorized ser ice in order to adjust the scale.
11. Adjusting the scale
Adjusting (calibration) scale should be made if the scale precision is
not sufficient. A standard of mass should be used with Max alue taken
from scale technical data table. In case of legalized scales with
inaccessible calibration (secure seal) a contact with ser ice is
recommended.
12. Accumulator change (option)

13. Connection with computer or printer (option)
In order to send data to external de ices the scale is equipped with RS232C or
RS485 (option) connection.
The scale sends weighing result when initial signal form computer appears or
key of the scale is pressed.
During cooperation with printer data is sent automatically after a sample is put on
and scale indication becomes stable. Next transmission is possible after sample is
taken off. Successi e measurement number and weighing result (look at setting
serial port parameters) are sent.
In special execution the scale can be equipped with second connection. Additional
connection can be used for continuous data transmission of measurement results to
additional display.
To cooperate with scale computer must ha e a processing data from scale
programme. This types of programmes are a ailable from producer.

The B/G button allows for reading
gross weight.
Caution:
Repressing the B/G button switches
the scale to the net weight display.
14.3 Balance resolution increasing
The HR button causes the momentary
result displaying (approx. 5 seconds)
with the maximum resolution,
allowed by the balance processor.
That button is especially useful in the
legalized balances with d=e reading
graduation.
The increased resolution result is the
